Application ilerl October 2S, 1884.

(No model.;

To all whom it may concern:

Be it known that I, DENNIS E. MAcGARTnY, a citizen ofthe United States, residing at Maplewood7 inthe county of Middlesex and State 5 of Massachusetts, have invented certain new and useful Improvements in Mand1'els;and I do hereby declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to 1o which it appertains to make and use the same.

My invention relates to the art of forging; and the nature thereof consists in providing a conical mandrel, or a mandrel having the form ot' a conical frustunn, with a groove cxi5 tending the whole length of the exterior thereof from top to'bottorn for the purpose of fai clitating the making of rings orforgings having an interior circular form.

In the accompanying drawmg, the figure 2o illustrates a mandrel having my improvement applied thereto.

The mandrel A, which in this instance is the frustum of a conc, is made of cast-iron,

and has formed upon its exterior a groove sunk one or two inches below the surface, and 25 equal in length to the slant height of the frustum. This groove allows room for the tongs which hold the ring or other article to be forged or the eyebolt which may be upon it,

and thus allows the forging to beconveniently 3o held by the tongs, or permits the eyebolt to be within the slot or groove.

Having thus described my invention, I claim and desire to secure by Letters Patent- A forging-mandrel having a groove formed 35 on and beneath its exterior surface, as and for the purpose described.

In testimony whereof Iaitix mysignature in presence of two Witnesses.

DENNIS E. MACOAETHY.
